Physical properties
Hardness of 6 on the Mohs scale, composed mostly of quartz, alkali feldspar, and plagioclase, with a phaneritic (coarse-grained) texture. Colors typically range from pink to gray depending on the feldspar content.
Formation & geological history
Formed from the slow crystallization of magma far beneath the Earth's surface over millions of years.
Uses & applications
Widely used in construction for countertops, flooring, curbing, and monuments due to its durability and aesthetic appeal.
Geological facts
Granite is the most common rock type in the Earth's continental crust and forms the core of many mountain ranges.
Field identification & locations
Easily identified by its speckled, interlocking crystal grains of pink, white, and black minerals. Found globally in ancient shields and mountain roots.
